Controversial and revolutionary book I have (7)
I believe the answer is:
emotive
'controversial' is the definition.
(I've seen this before)
'revolutionary book i have' is the wordplay.
'revolutionary' says the letters should be written backwards.
'book' becomes 'tome' (a tome is a book).
'i have' becomes 'I've' (contraction of 'I have').
'tome' back-to-front is 'emot'.
'emot'+'ive'='EMOTIVE'
'and' is the link.
(Other definitions for emotive that I've seen before include "Contentious" , "Arousing strong feeling" , "able to get going" , "arousing passion" , "Generating feelings" .)
